Sec. 60.283  Standard for total reduced sulfur (TRS).

    (a) On and after the date on which the performance test required to 
be conducted by Sec. 60.8 is completed, no owner or operator subject to 
the provisions of this subpart shall cause to be discharged into the 
atmosphere:
    (1) From any digester system, brown stock washer system, multiple-
effect evaporator system, or condensate stripper system any gases which 
contain TRS in excess of 5 ppm by volume on a dry basis, corrected to 10 
percent oxygen, unless the following conditions are met:
    (i) The gases are combusted in a lime kiln subject to the provisions 
of paragraph (a)(5) of this section; or
    (ii) The gases are combusted in a recovery furnace subject to the 
provisions of paragraphs (a)(2) or (a)(3) of this section; or
    (iii) The gases are combusted with other waste gases in an 
incinerator or other device, or combusted in a lime kiln or recovery 
furnace not subject to the provisions of this subpart, and are subjected 
to a minimum temperature of 650 [deg]C (1200 [deg]F) for at least 0.5 
second; or
    (iv) It has been demonstrated to the Administrator's satisfaction by 
the owner or operator that incinerating the exhaust gases from a new, 
modified, or reconstructed brown stock washer system is technologically 
or economically unfeasible. Any exempt system will become subject to the 
provisions of this subpart if the facility is changed so that the gases 
can be incinerated.
    (v) The gases from the digester system, brown stock washer system, 
or condensate stripper system are controlled by a means other than 
combustion. In this case, this system shall not discharge any gases to 
the atmosphere which contain TRS in excess of 5 ppm by volume on a dry 
basis, uncorrected for oxygen content.
    (vi) The uncontrolled exhaust gases from a new, modified, or 
reconstructed digester system contain TRS less than 0.005 g/kg air dried 
pulp (ADP) (0.01 lb/ton ADP).
    (2) From any straight kraft recovery furnace any gases which contain 
TRS in excess of 5 ppm by volume on a dry basis, corrected to 8 percent 
oxygen.
    (3) From any cross recovery furnace any gases which contain TRS in 
excess of 25 ppm by volume on a dry basis, corrected to 8 percent 
oxygen.
    (4) From any smelt dissolving tank any gases which contain TRS in 
excess of 0.016 g/kg black liquor solids as H2S (0.033 lb/ton 
black liquor solids as H2S).
    (5) From any lime kiln any gases which contain TRS in excess of 8 
ppm by volume on a dry basis, corrected to 10 percent oxygen.
